Crews at the region's air ambulance charity, where the Duke of Cambridge works as a pilot, have moved to a new base which should help improve their life-saving capabilities.
Since the charity's launch in 2000, the East Anglian Air Ambulance (EAAA) has been based in an old hangar at Cambridge Airport.
The team has moved to a new purpose-built base on the site and say it will help them respond more quickly and efficiently to 999 emergencies.
Former RAF search and rescue pilot William, who is known to colleagues as Captain William Wales, has flown dozens of missions since joining the charity as a co-pilot in July.
Five months on, he is regarded as 'one of the team' and has kept a low profile, stressing he wants to concentrate on his duties.
The teams respond to a wide range of incidents with trauma injuries making up the majority of the work.
They also treat many patients for cardiac arrests and in recent years have seen an increase in calls to deal with people who have mental health issues and attempted suicides.
